| Abstract: | In this paper, a class of parallel implicit Runge-Kutta methods is constructed for a multiprocessor system. A parallel two-stage Runge-Kutta formula which possesses a three-order accuracy is given out. It is proved that this computational formula is of A- Stability. The numerical results show that this formula is efficient for solving stiff ordinary differential equations. |
